We stayed 7 weeks in Andrew's apartment with our 2 kids and we had a great time there. The location is perfect, very close to the BTS and Silom road, and there is a large market in the street where you can find street food anytime.
The apartment is just as the description and the swimming pool is great, especially with the kids.
Andrew always answered our questions very quickly and was very helpful and friendly when we arrived in Bangkok even tough he was in Europe. Highly recommended !
